Aluminum: Ore, Refinery, Mining SchoolWorkHelper

Aluminum is made when refining alumina, which is in turn found from the ore ‘bauxite’. Bauxite is often mined in the opencast method. Aluminum deposits are found in many countries, but the countries with significant deposits include: Guinea, Jamaica, Surinam, Australia and Russia. How is Aluminum refined?
